JDsGX

I have an '04 GX with the ML sound system. I'm reasonable happy with the sound except the 6-disc CD player doesn't work. I play CD's through the DVD player. A couple of months ago, the nav screen went blank and no audio from the radio. I checked the fuses and none were blown. At least not then. After reading tons of listings on another forum, I figured my amplifier was toast. Today, I went out to look at some of the other fuses besides radio 1 and 2. They were all fine, but radio 2 was now blown. I replaced that one, which instantly blew, or so I thought. I turned on the ignition and the nav screen came on briefly, then went blank again. I then disconneced the battery and put another fuse in. I heard what I thought was another fuse blowing. However, when I went to the store this evening, the nav screen came on. The backup camera works. I turned on the radio, but still no audio. I am assuming my amp is toast. Am I correct? Or is it the radio itself? No, I don't want to swap it out for one of the Android systems out there. It may look nice, but I'm not spending $1k and up on a radio. Any advise from those who have had a similar problem are appreciated. And I know you are out there as we all know the ML system is not too good this long after it was made.

The owner's manual says premium. I can understand the temptation to use regular with the 20-30 cent price difference. However, if you car has over 100K miles, it probably has a fair amount of carbon buildup in the heads. Using regular will probably cause pinging. That's not good for your valves. What you might save in gas will not pay for the valve job you will soon need. Figure $1K at least. Much more at the dealer. To cut the cost, especially here in CA with our high prices, I go to Costco or Sam's Club. The price difference is at least .30 less. Before the prices went up, it was a much as .70 less. Definitely worth the cost of the membership. A couple of fillups will cover the membership.
